Description

Technical Field

[0001] This utility model relates to the technical field of air outlets, and in particular to an anti-condensation swirl air outlet. Background Technology

[0002] Existing anti-condensation swirl vent structures, such as the one disclosed in Chinese Patent Publication No. CN206583057U on October 24, 2017, include a vent panel with multiple air outlets arranged radially from the center. A central cover is located at the bottom of the central area of ​​the vent panel, with an insulation gap between the central cover and the vent panel. When the swirl vent delivers low-temperature air in a radiating direction, a negative pressure area appears below the central cover, inducing the indoor airflow to mix with the low-temperature air. When the dew point temperature of the indoor airflow is higher than the temperature of the central cover, condensation occurs on the central cover. Therefore, the existing swirl vent structure needs further improvement. Utility Model Content

[0003] The purpose of this invention is to provide an anti-condensation swirl air outlet.

[0004] The purpose of this utility model is achieved as follows:

[0005] An anti-condensation swirl air vent includes an air vent panel with multiple air outlets arranged radially from the center. A central cover, made of metal, is located at the bottom of the central area of ​​the air vent panel. A heat-insulating baffle cover, covering the bottom and sides of the central cover, is also provided at the bottom of the central cover. This anti-condensation swirl air vent effectively insulates the central cover by providing a heat-insulating baffle cover on its outer side, covering both the bottom and sides. This also guides the rising hot air to the perimeter of the air vent, preventing direct contact between indoor airflow and the low-temperature surface of the central cover, thus effectively preventing condensation.

[0006] The present invention can be further improved in the following ways.

[0007] The side of the heat insulation baffle cover has a baffle protrusion extending radially. The baffle protrusion effectively blocks the rising hot air and guides the hot air to the perimeter of the air outlet panel, preventing hot and cold air from converging near the center cover.

[0008] The air vent panel has multiple fan blades arranged in a ring at intervals, with the air outlet located between two adjacent fan blades. The fan blades are rotatably mounted on the air vent panel.

[0009] The heat-insulating baffle cover is made of plastic, which has excellent heat insulation properties, thus keeping the central cover warm.

[0010] The heat-insulating baffle cover and the baffle protrusion are integrally formed, so the heat-insulating baffle cover of this utility model is easy to process and has low production cost.

[0011] The diameter of the baffle protrusion is larger than the diameter of the heat-insulating baffle cover.

[0012] The heat-insulating baffle cover includes a bottom wall and a surrounding wall. The lower end of the surrounding wall is connected to the edge of the bottom wall. The surrounding wall covers the side of the center cover, and the bottom wall covers the bottom of the center cover. The baffle protrusion is located radially along the edge of the bottom wall.

[0013] The heat-insulating baffle is adhered to the center cover, so the heat-insulating baffle of this utility model is easy and reliable to fix.

[0014] The fan blades are made of metal, and the end of the fan blades near the center cover is equipped with a first layer of insulation cotton. The insulation cotton effectively keeps the end of the fan blades near the center cover warm and prevents condensation from forming on that end.

[0015] The baffle is located directly below the end of the fan blade near the center cover. The baffle can effectively block the rising hot airflow from passing through one end of the fan blade, thus preventing condensation from forming on that end.

[0016] The inner wall of the center cover is equipped with a second layer of insulation. This insulation material has excellent heat insulation properties, keeping the center cover warm and preventing condensation.

[0017] The beneficial effects of this utility model are as follows:

[0018] This utility model of an anti-condensation swirl air outlet features a heat-insulating baffle cover on the outside of the central cover. The heat-insulating baffle cover covers the bottom and sides of the central cover, effectively insulating and heat-preserving the central cover, and also guiding the rising hot air to the perimeter of the air outlet. This prevents the indoor airflow from directly contacting the low-temperature surface of the central cover, thus effectively preventing condensation on the central cover. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Example 1, as Figures 1 to 3As shown, an anti-condensation swirl air outlet is installed at the bottom of the air box 6. It includes an air outlet panel 1, on which multiple air outlets 10 are provided. The multiple air outlets 10 are arranged radially in the center of the air outlet panel 1. A center cover 3 is provided at the bottom of the central area of ​​the air outlet panel 1. The center cover 3 is made of metal. A heat insulation baffle 2 is provided at the bottom of the center cover 3. The heat insulation baffle 2 covers the bottom and sides of the center cover 3.

[0024] This is a more specific technical solution of the present invention.

[0025] The heat insulation baffle 2 has a baffle protrusion 7 extending radially on its side. The baffle protrusion 7 effectively blocks the rising hot air and guides the hot air to the periphery of the air outlet panel 1, preventing hot and cold air from converging near the center cover 3.

[0026] The air vent panel 1 is provided with a plurality of fan blades 11 arranged in a ring at intervals. The air outlet 10 is located between two adjacent fan blades. The plurality of fan blades 11 include a plurality of fixed fan blades 4 and a plurality of movable fan blades 5. The fixed fan blades 4 and the movable fan blades 5 are arranged coaxially. The fixed fan blades are fixed on the air vent panel 1, and the movable fan blades 5 are rotatably arranged on the air vent panel 1. The movable fan blades 5 are used to change the direction of the airflow at the air outlet 10 and the size of the air outlet. When the movable fan blades 5 rotate to above the fixed fan blades 4, the movable fan blades 5 fold above the fixed fan blades 4, and the air outlet 10 becomes larger. At this time, the airflow direction of the air outlet 10 is vertically downward. At this time, there is no rising hot airflow in the area directly below the air vent panel 1, and the center cover 3 will not condense.

[0027] When the movable fan blade 5 rotates to be offset from the fixed fan blade 4, the air outlet 10 becomes smaller. At this time, the airflow direction of the air outlet 10 changes to blow towards the perimeter of the air outlet panel. At this time, the hot airflow in the area directly below the air outlet panel 1 rises. The heat insulation baffle covers the bottom and sides of the center cover, effectively insulating the center cover. In addition, the baffle protrusion 7 effectively blocks the rising hot air and guides the hot air to the perimeter of the air outlet panel 1, preventing hot and cold air from converging near the center cover 3, and effectively preventing condensation on the bottom and sides of the center cover 3.

[0028] The heat-insulating baffle cover 2 is made of plastic, which has a good heat insulation effect, and keeps the central cover 3 warm.

[0029] The heat insulation baffle 2 and the baffle protrusion 7 are integrally formed, so the heat insulation baffle 2 of this utility model is easy to process and has low production cost.

[0030] The diameter of the baffle 7 is larger than the diameter of the heat insulation baffle cover 2. The baffle 7 effectively blocks the rising hot air and guides the hot air to the perimeter of the air outlet panel 1, preventing hot and cold air from converging near the center cover 3 and effectively preventing condensation on the bottom and sides of the center cover 3.

[0031] The heat-insulating baffle cover 2 includes a bottom wall 21 and a surrounding wall 22. The lower end of the surrounding wall 22 is connected to the edge of the bottom wall 21. The surrounding wall 22 covers the side of the center cover 3, and the bottom wall 21 covers the bottom of the center cover 3. The baffle protrusion 7 is provided radially along the edge of the bottom wall 21.

[0032] The heat insulation baffle 2 is bonded to the center cover 3, so the heat insulation baffle 2 of this utility model is easy and reliable to fix.

[0033] The movable fan blade 5 is made of metal. The end of the movable fan blade 5 near the center cover 3 is provided with a first insulation cotton 8. The insulation cotton effectively insulates the end of the movable fan blade 5 near the center cover 3 and prevents condensation from forming at the end of the movable fan blade 5.

[0034] The baffle 7 is located directly below the end of the movable fan blade 5 near the center cover 3. The baffle 7 can effectively block the rising hot airflow from passing through one end of the movable fan blade 5, thus preventing condensation from forming on one end of the movable fan blade 5.

[0035] The inner wall of the center cover 3 is provided with a second insulation cotton 9. The second insulation cotton has a good heat insulation effect, which keeps the center cover 3 warm and prevents condensation.
